The message
from "john west++++" contains these words:

hi, i would like to protect from the cold two potted plants at the rear of
the house. (south facing). my plan is to put large clear plastic bags
completely over the plants and
their pots.

I would like advice please on should I block up the six or so small holes
originally put in the bag by the manufacturer; to help keep the cold
out, or will that interfere with any necessary air flow to the plants?

also would it be best to stand the clay pots directly on to the concrete
patio slabs or
should I insulate the post from the slabs with a piece of wood, please?

If you're going to wrap them, I'd make tubes up out of two or three
layers of wound-round small bubblewrap and tie up the tops, and stand
the pots on thick expanded polystyerine.

You can usually get both (waste packaging) from white goods and telly shops.
